国产某超超临界汽轮机配汽机构出厂的流量特性曲线仅适用于带基本负荷的机组。通过现场试验研究,对制造厂新增的流量特性曲线进行了修正,并确定出该机组在新阀序下不同负荷对应的最佳主蒸汽压力和相应的最佳初压全程实施方案,以提高机组变工况下的运行经济性,对同类型机组运行方式的优化提供了借鉴。 Domestic ultra-supercritical steam turbine steam turbine factory flow characteristics of the curve is only applicable to units with basic load. Through the field test and study, the new flow characteristic curve of the manufacturer was amended and the optimal main steam pressure corresponding to different loads under the new valve sequence and the corresponding optimal initial pressure full-scale implementation plan were determined to improve The operating economy of the unit under varying conditions provides reference for the optimization of the operation modes of the same type units.
